1. The sand scraper is added to match the drum feeder of the ball mill, so that the sand pulp flows to the drum feeder of the mill from the side.
2. It adopts rolling bearing, ZQ or ZL speed reducer, reducing the frictional resistance and installation and maintenance time.
3. Improved lubrication parts, dry oil pump for large-specification products.
Remarks: 1. Please mark out the model, quantity and spiral direction of the classifier while ordering. 2. The lengthened type (lengthening of sand return zone, lengthening of settling zone) can be designed and made according to customer demands, and the lengthening amount should be noted.

hydrocyclone design mainly shows in the following works:
1. Classification for section I closed circuit grinding
2. Classification for section II closed circuit grinding
3. Regrinding for fine mine classification
4. Mud-removing before selection and after selection
5. Dam and backfill for gangue
 

A typical hydrocyclone design consists of a conically shaped vessel, open at its apex, or underflow, joined to a cylindrical section, which has a tangential feed inlet. The top of the cylindrical section is closed with a plate through which passes an axially mounted overflow pipe. The feedis introduced under the pressure through  the tangential entry which imparts swirling motion to the pulp. This generates a vortex in the cyclone. The light granules will be pulled out by a pump through the overflow pipe, while the heavy particles will be discharged with the pulp through the underflow discharge
